Initial thought: they want a competitive race. Ted and his supporters have been fairly civil to every Republican who has entered the race.
Ted is not to be expected to run a routine campaign, he is a genius. Maybe the two of them plan to team at the debates. Carly has to make it into the main debate maybe Ted is just helping her make it.
She’s can hit Clinton with some shots that a male candidate would be called sexist by the media!
She’s very effective and keeping her alive as a candidate only helps the general cause of defeating the Democrats.
